Calculate the mean and standard deviation of the sampling distribution of p?
Use technology to help you test the claim about the population mean, p, at the given level of significance, a, using the given sample statistics. Assume the population is normally distributed. Claim: u > 1280; a = 0.07; o = 196.31. Sample statistics: x= 1308.11, n= 200 H p> 1280 Ha: p 1308.11 O D. Ho: Hs 1308.11 Ha ps 1308.11 Ha: p> 1308.11 O E. H, p> 1280 O F. Ho: µ2 1280 Ha: u< 1280 Ha ps 1280 Calculate the standardized test statistic. The standardized test statistic is 2.03. (Round to two decimal places as needed.) Determine the P-value. P 3D (Round to three decimal places as needed.)
Provide two synonyms for “the distribution of all possible sample means for samples of a given size.”
Use technology to help you test the claim about the population mean, , at the given level of significance, a, using the given sample statistics. Assume the population is normally distributed.

A time analyst for the Super-Fast speedway pit crew observed the mechanic in charge of changing both front tires during a pit-stop practice session. The mechanic’s job is divided into six work elements and a preparation time between drills. The element times (in seconds) for the first six cycles are shown in Table.a. Calculate the normal time for changing tires.b. What sample size is appropriate for estimating the average time for work element 3 within +-1 percent of the true mean with 99 percent confidence?c. What is the standard time for changing tires if the allowance is 20 percent?
prove the theorem show that the sample mean is unbiased estimated of the population mean in normal distribution.....
What are the population parameters? Pick one: The difference in the sample sizes The difference in the two sample means The mean time spent for all test-takers before and after tutoring The mean time spent for all test-takers before and after tutoring combined Does sufficient or insufficient evidence exist?
4. For the following information, determine whether a normal sampling distribution can be used, where p is the population proportion, α is the level of significance, p is the sample proportion, and n is the sample size. If it can be used, test the claim. Claim: p>0.44; α=0.08. Sample statistics: p=0.52, n=350 Question content area bottom Part 1 Let q=1−p and let q=1−p.

What conditions are necessary in order to use a one-way ANOVA test? Which conditions below are necessary? Select all that apply. □ □ □ A. The sample sizes must be equal. B. Each population must have the same variance. C. There must be at least 3 samples. D. The sample must be randomly selected from the same population. E. The samples must be randomly selected from a normal, or approximately normal, population. F. The samples must be independent of each other.
Practice Exercise A. Consider the population consisting of values (1, 3, 4). The sample size is 2 from this population. Compute the following: 1. Mean of the sampling distribution of the means 2. Variance of the sampling distribution of the means 3. Standard deviation of the sampling distribution of the means
